How many calories are in 1 gram of fat?

  1. 2 calories

  2. 4 calories

  3. 7 calories

  4. 9 calories

The correct answer is: 2 calories

1 gram of fat contains 9 calories, making 9 calories the answer to the above question. B is incorrect because it says 4 calories, which is the amount of energy in 1 gram of carbohydrate. C and D are incorrect because they provide a higher number of calories, which is the amount of energy that is found in 1 gram of oil, butter, or another type of fat. The correct answer is A because it accurately reflects the amount of energy found in 1 gram of fat. This is important to know when watching calorie intake and managing one's diet.
